NAIL LACQUERS
Definition:
Nail lacquers or nail paints may be defined as viscous or
semi-liquid preparations that are intended for the decoration of the nails of
the fingers and toes. Nail lacquers form the most commonly used the most
popular type of manicure preparations. Nail polishes are quite distinct from
those of nail lacquers and are regarded as a type of manicure
preparations that produce
a gloss by means
of huffing action.
The action is mainly by causing abrasion on the surface of the nail and
secondly by drawing more blood into the capillaries of the nail.
Ideal Properties of Nail Lacquer:
The ideal properties of a nail
lacquer should be as follows:
·
It
should be safe for the skin and nails and should not lead to any harmful
effects.
·
It
should be easy to apply and easy to remove.
·
It
shall maintain its properties even during long storage. Hence, an efficient
nail lacquer should possess consistent stability.
·
The
most important property is that it should form a uniform and satisfactory film
on the nails.
·
It
should have good wetting and flow properties and should be viscous in nature in
order to form an appropriate film.
·
The
distribution of the colour should be uniform which can be achieved by using
finely divided pigments that are uniformly ground and evenly wetted by the
solvent.
·
It
should provide a good shine on the nail on application.
·
It
should possess sufficient adhesive property so that it may uniformly adhere to
the nail without slipping.
·
It
should possess the required flexibility so that it may not become brittle and
crack upon application.
·
The
surface should be sufficiently hard in order to prevent th6 effect of impact
and scratch.
·
The
drying time of the film should not be too rapid or too slow; say about -
minutes without forming any bloom.
It should be able to preserve all
these properties at least for a week after its application.
